There is danger from future widespread use of nanotechnology. It is seen as the new savior to save the world from food shortages and so on. But like bio-fuel production it could do more harm than good. CSIRO is calling for more study of nanotechnology. This is despite the fact that no country has yet examined safety issues involved with it.

Nanotechnology creates "micro-fine" products that have no safe disposal system. If they get into the environment there is not telling what damage they could do.

Risks are seemingly endless: use by terrorists; environmental damage; self-reproduction (goo everywhere); even the future of Mankind on this planet could be under threat.

Once a material has been modified or a new nano-product created it becomes a permanent structure. It must be chemically altered to make it safe. A nano-substance is not inert. It will act on the environment if it can. At the moment there are no restrictions. Developers can do what they wish. Let's hope regulations are put in train before a disaster occurs.
